Grant Van Horn PhD Research Engineer
Grant uses data in the Macaulay Library to prototype machine learning applications that can be utilized and deployed throughout the Cornell Lab of Ornithology. His research focuses on the detection and identification of wildlife in images, audio, and video. His passion lies at the intersection of human-machine collaboration, where the collective strengths of humans and machines can be used to answer questions from data.
Drew Weber Merlin Project Coordinator
Drew works on Merlin Bird ID, charting out new features to help users learn more about birds, and collaborating with partners to expand the app to the rest of the world. Drew also manages web projects for the eBird and Macaulay Library teams. Drew has been birding since he was a kid and loves anything with birding and technology, so he feels fortunate to combine these two things every day.
Mike Webster, PhD Macaulay Library Director and Robert G. Engel Professor of Ornithology
As Director, Mike oversees the various archival, collections development, and research/outreach activities of the Macaulay Library. He is also a Professor in the Department of Neurobiology and Behavior, with research focusing on the behavior and evolution of birds (particularly Australian fairy-wrens and New World warblers). Learn more about his research.
Karen Workman Financial Analyst
Karen oversees the financial management of the Macaulay Library and other units including the budgetary process, grant and contract administration, financial reporting, and assisting in the preparation of award proposals.
Students and Postdoctoral Researchers
Carrie Branch Rose Postdoctoral Fellow
Carrie is a behavioral ecologist interested in the evolution of signaling and cognition. At Cornell, Carrie is investigating whether females use secondary sexual signals to identify and mate with males that have superior spatial cognition, a trait required for overwinter survival in food-caching birds. She addresses these questions in free-living mountain chickadees that inhabit differentially harsh winter climates in the Sierra Nevada.
Alicia Brunner PhD Candidate
Alicia researches the impact of environmental change on the behavior of Neotropical migratory birds. While completing her M.Sc. at Ohio State, she studied how wintering Swainson’s Warblers respond to changes in seasonal precipitation by adjusting their space use. At Cornell, she will be investigating how climate change is influencing the timing of breeding, molt, migration, and potential life-history tradeoffs using the long-term study system of Black-throated blue warblers at Hubbard Brook Forest, NH
Jay Falk PhD Student
Jay is an evolutionary biologist and behavioral ecologist investigating how and why differences between the sexes arise. Visit Jay’s website.
Ryan Germain, PhD Postdoc
Ryan’s research focuses on understanding variation in reproductive success and survival among individuals within wild animal populations.
Russell Ligon, PhD NSF Postdoctoral Fellow
Russell is a behavioral evolutionary biologist interested in understanding how animals communicate and how animal communication strategies influence patterns of diversification. Visit his website.
Karan Odom, PhD Postdoc
Karan investigates how songbirds evolved the diversity of complex songs we see today. Karan is especially interested in the selection pressures responsible for song in females and males. Karan uses comparative methods and recordings from sound archives to examine how female and male songs changed over time. Karan developed a citizen science project—the Female Bird Song Project—to increase awareness and documentation of female bird songs.
Madelyn Ore PhD Candidate
Madelyn is interested in investigating how neotropical migrant birds are adapting to changing climate and the lengthening of the green period during the breeding season. She is using a combination of genomic tools and ecological experiments to address this question in the Black-throated Blue Warbler.
Young Ha Suh PhD Candidate
I am a Ph.D. student co-advised by John W. Fitzpatrick and Mike Webster. I am interested in why behavioral variation exists among individuals and how environmental change plays a role in its maintenance. My current research focuses on the variation of dispersal behavior in the Florida Scrub-Jay, a species that inhabits a dynamic habitat altered by frequent fires. Using field observations and modeling approaches, I am looking at the causes and consequences of dispersal decisions in relation to the social and physical environment.
Derrick Thrasher PhD Candidate
Derrick earned his bachelor’s degree in Wildlife Ecology and Conservation from the University of Florida. His undergraduate research in Katie Sieving’s lab focused on territorial interactions and habitat use of the eastern Painted Bunting in Florida. Derrick is now pursuing a Ph.D. in the Webster lab. His interests relate broadly to sociality and the evolution of social signals in birds. Currently, Derrick is investigating the role of social selection on the evolution of female plumage ornaments and reproductive strategies in the Variegated Fairy-wren.
Joseph Welklin PhD Candidate
Joseph is a behavioral ecologist interested in the causes and consequences of individual variation within animal species, especially in fairy-wrens.
